Abstract
Sampleso f Anophelesg ambiaes .l. werec ollectedf rom eight localitiesb elongingt o four of the five main ecologicasl tratao f Ghana.A nalysiso f ovarianp olytenec hromosomesre vealedt he presenceo f A. gambiae s.s. in all the sites studied, while l. arabiensisw as detectedo nly in the extremen orthern locality of Navrongoa nd l. rnelasin somes outherns ites.A nopheleas rabiensis howeda degreeo f inversionp olymorphism comparablet o the one observedin other WestA frican countries.T he analysiso f the chromosomal polymorphism of A. gambiaes .s.s howedt he presenceo f the FOREST form in the rain forest localities and the SAVANNA form in the coastal savanna sites. The MOPTI form occurred sympatrically with the SAVANNA form in the northernmostl ocality. The possiblei nfluenceo f the presenceo f various taxa of the A. gambiaec omplexa nd oftheir intra-specificv ariantso n malaria vectorials ystemis discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
